Application filed June 22, 1916.

To all whom it may concern:

Be it known that we, JOHN B. Monnow and OLAUS P. Gnnrrz, citizens of the United States, residing at Brooklyn, in the county of Kings, State of New York, have invented a new and useful Umbrella, of which the following is a specification.

This invention relates to umbrellas and more especially to means for detachably securing the ribs and stretchers to the fixed and slidable sleeves respectively on the rod. The ribs and runners have generally been fastened by means of wires extending through eyes therein but these wires become broken and release the parts.

One of the objects of the present invention is to provide ball and socket connections for the ribs and stretchers whereby the parts can work freely, will not become accidentally detached, and whereby any one of the ribs or stretchers can be easily detached when desired without requiring any particular skill.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, withv out departing from the spirit of the invention. 7

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is an elevation of a portion of the rod of an umbrella and showing a rib and a stretcher connected thereto by the particular means constituting the present in vention.

Fig. 2 is an enlarged longitudinal section through one of the connections.

Fig. 3 is a section on line A-B Fig. 2.

Fig. 4 is a section on line 0-D Fig. 2.

Fig. 5 is a side elevation of one of the connections, the parts thereof being shown separated to permit the insertion or withdrawal of the ball end of a rib or stretcher.

Referring to the figures by characters of reference 1 designates a portion of the rod of an umbrella and slidably mounted on this rod is a sleeve 2 provided at one end with a collar 3 and, at an intermediate point,

with an annular enlargement &. This an nular enlargement has a series of sockets 5 in one face thereof and radial. slots 6 QX- tend from these sockets to the periphery of the enlargement t. A cap 7 in the form of a ring is movably mounted on the sleeve between enlargement 4 and collar 3 and has radial slots 8 designed to register with the slots 6. Each of the sockets 5 is of a depth substantially equal to the diameter of a ball 10 provided at the inner end of a stretcher 11 and it will be apparent that when the cap is in position upon the enlargement 1 the balls 10 will be retained in the sockets 5 although the ribs 11 will be free to swing within the slots 6 and 8. For the purpose of holding the cap 7 against rotation relative to the enlargement a, a key 12 is secured within the cap 7 and extends into a groove 13 in the periphery of the enlargement 4.

Opposed rounded ears 14 are extended from the cap 7 and are adapted to be engaged by corresponding cars 15 formed upon a holding ring 16 which is mounted on the sleeve 2 and bears against the collar 3. A screw 17 extends through the ring 16 and into the sleeve 2 for the purpose of holding ring 16 against movement relative to the sleeve and with the ears 15 bearing against the ears 14. WVith the parts thus positioned the cap 7 will be pressed tightly against the enlargement 4: and the balls 10 cannot become displaced. However. by removing the screw 1.7 and rotating ring 16, the cars 14 can be shifted to position between the ears 15, thus removing the cap 7 a .suflicient distance from enlargement 4 to allow the balls 10 to be lifted out of the sockets 5 and removed from engagement with the enlargement.

Secured to the rod 1 near one end thereof is a sleeve 18 having a collar 19 at one end and provided with an annular enlargement 20 near its other end similar to the enlargement 4 hereinbefore described and having a cap 21 similar to the cap 7 A locking ring 22 is likewise provided and when this ring is in one position it serves to hold the cap 21 pressed against the enlargement 20 and, when in its other position, it permits the cap to be shifted away from the enlarge ment, thus to allow the withdrawal of balls at the inner ends of ribs 23. In other words, the same means is employed for attaching the ribs 23 to the rod 1 as is provided for attaching the stretchers 11 to the slidable sleeve 2. I 1

It will be obvious that by providing connecting means such as herein described, any one of the ribs or stretchers can be readily removedand replaced and there is no danger of the parts becoming accidentally separated. Furthermore the ball and socket connections provide a structure which will work easily and will not be undesirably bulky.

What is claimed is In an umbrella, the combination with a member having an annular enlargement provided with sockets in one face and radial slots extending from the sockets, of elements having ball ends seated within the respective sockets, a cap bearing against the en- Copies of this patent may be obtained for largement on the member and having slots registering with the slots in the enlargement, a holding ring movably mounted on the member, ears extending from the cap, ears extending from the ring and cooperating with the ears on the cap to hold said cap pressed against the enlargement on the memher, and means for holding the ring against movement relative to the cap.

In testimony that we claim the foregoing as our own, we have hereto aflixed our sig natures in the presence of two witnesses.
